Our Graphite Petroleum Coke (GPC) offers measurable production benefits. It resolves major industry pain points in cost savings, quality improvement, stable manufacturing and environmental protection, making it the preferred choice for global industrial buyers seeking long-term cooperation.

1.Superior Cost Performance

• Carbon absorption exceeds 90%, 10–20% higher than conventional carburizers.
• Cut your overall expenses: shorter smelting cycles and lower power & fuel usage.

2.Exceptional Purity

• Fixed Carbon: 98%–99.5% | Sulfur: 0.03%–0.08%
• Minimize production flaws: avoids casting pores and cracks to raise finished product yield.

3.Reliable Consistent Performance

• Manufactured at 2800°C–3000°C graphitization temperature, delivering strong oxidation and thermal shock resistance.
• Uniform quality across batches, ideal for non-stop 24/7 mass production.

4.Eco-Conscious & Fully Customizable

• Low volatile content generates minimal harmful emissions, meeting global environmental standards.
• Flexible specifications: powder, granular and lump sizes available to suit all production requirements.

1. Steel & Metallurgy: Premium Choice for High-Grade Alloys

As a top-grade carbon raiser for steelmaking, our ultra-high purity Graphitized Petroleum Coke (GPC) is extensively adopted to produce carbon steel, alloy steel, stainless steel and special steel.

• Why our GPC stands out

Stable carbon content paired with ultra-low sulfur and nitrogen impurities allows precise carbon control in molten steel. It refines the internal structure of steel, boosts strength, hardness and toughness, and lowers risks of porosity and segregation.

• Typical applications: High-grade structural steel, industrial steel and special steel production.

2. Precision Casting: Raise Output & Lower Defect Rates

GPC works as an efficient carbon raiser and nucleating agent for gray iron, ductile iron and steel casting.

• Performance advantages

It encourages even graphite separation and grain refinement, optimizes metallographic structures and enhances casting compactness, wear resistance and mechanical performance.

• Typical applications: Cuts common casting flaws such as pores, sand holes, cracks and shrinkage cavities. Well-suited for wind power castings, automotive components and heavy machinery parts.

3. Aluminum Electrolysis & Non-Ferrous Metallurgy: Reduce Energy Consumption

Thanks to outstanding electrical and thermal conductivity plus ultra-low impurity levels, GPC is perfectly suited for cathode materials in aluminum electrolytic cells and non-ferrous metal smelting.

• Energy-saving benefits

It lowers cell resistance and power consumption while raising current efficiency. It avoids impurity contamination and helps manufacturers produce high-purity primary aluminum.

• Typical applications: Cathode filler, reducing agents and fluxes, supporting energy conservation and better product quality across metallurgical operations.

4.New Energy & Advanced Materials: Fuel Sustainable Development

High-purity, highly graphitized GPC acts as high-quality raw material for artificial graphite and lithium-ion battery anode materials.

• Technical strengths

Its stable crystal structure, great conductivity and reliable cycling performance satisfy production standards for power batteries and energy storage devices.

• Typical applications: Further processed into power battery anodes, energy storage graphite electrodes and thermal conductive graphite materials with broad market prospects.

5.Refractories & Special Graphite Materials: Fundamental Industrial Carbon Material

GPC is also widely used to manufacture graphite crucibles, graphite moulds, refractory carbon materials and conductive coatings.

• Versatile usability

It covers a wide range of industrial scenarios and serves as an essential base material within the carbon industry chain.

• Complete quality control system guarantees stable quality of our graphite petroleum coke.

Founded in 2017, we are a large professional carbon goods manufacturer and exporter covering R&D, production and global export, with over 9 years of manufacturing and international trade experience. We focus on supplying premium carbon materials, primarily Graphite Petroleum Coke (GPC) and artificial graphite.

Our plant is fitted with full modern production equipment: advanced high-temperature graphitization furnaces, precision screening machines and professional impurity testing devices. We manage the whole production chain in-house, from raw material selection, high-temperature graphitization and fine processing to classified packaging and final inspection.

We operate a strict standardized quality control system. Each shipment undergoes thorough testing of key parameters including fixed carbon, sulfur content, ash content, particle size and graphitization degree, guaranteeing consistent quality across all batches.

With ongoing technical upgrades and lean production management, we can deliver large volumes steadily over the long run and accommodate custom orders. Thanks to consistent reliable quality, competitive factory pricing and complete cross-border support, our products are shipped globally and trusted by metallurgy, casting and new energy enterprises for long-term cooperation.

1.Are the core parameters of your GPC stable? Is the batch difference large?

A: We conduct both automated testing and manual rechecks for all key indicators of our GPC. Batch-to-batch deviations are kept minimal, ensuring consistent product performance. Stable parameters allow our customers to run 24-hour continuous mass production without worrying about inconsistent quality between shipments.

2.Can you customize particle size, sulfur content and carbon content according to requirements?

A: We offer full customization services. We can adjust our GPC to meet your requirements on particle size (powder, granules, lumps), sulfur levels and fixed carbon content. Our products are customized to fit your production workflow and equipment, ideal for steelmaking, casting, aluminum electrolysis and new energy production.

3.Do you provide quality inspection reports before shipment? Is inspection acceptable?

A: We supply an official Certificate of Analysis (COA) for every shipment prior to delivery, listing all key product indicators. We welcome third-party lab testing, factory visits and on-site cargo inspection. Every batch of our products comes with fully transparent, traceable quality records.
